A comparative study of wireless mesh and adhoc network : A Cross layer design approach

摘要

Due to Wi-Fi marketing 802.11 becomes a universal solution for wireless connectivity. A wireless network is that in which the performance of a network depends on the layering structure of protocol. A wireless network is many types like Ad-hoc, cellular and mesh network. A mesh is used to optimize performance in better way as compare to traditional approach . A network can be optimized using different ?2 ways. Physical and mac layer are used for implementation. Physical layer consist of communication channel like TDMA, CDMA, OFDM, MIMO-OFDM etc each layer is designed independently and contain full transparency. A comparative study shows the best way of current technology in wireless network. Many algorithm are designed for QoS (Quality of services) in the wireless network. In this paper we compare ad-hoc and mesh network to show the pros & cons and their functionality on the basis of cross layer design approach.
